DETAILED DESCRIPTION

[0022] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 - Figure 4 As shown, a sample storage device includes a linkage mechanism and a placement mechanism arranged on a low temperature box 1, a cover plate 2 is arranged on the top of the low temperature box 1, the linkage mechanism is arranged on the inner wall of the low temperature box 1, the linkage mechanism is provided with two groups of connecting ropes 3, the connecting ropes 3 are turned by a first guide wheel 4 and a second guide wheel 5, and one end of the two groups of connecting ropes 3 are connected to the cover plate 2, and the other end of the two groups of connecting ropes 3 is provided with a support plate 6, the placement mechanism is arranged on the top of the low temperature box 1, and the placement mechanism is located directly above the linkage mechanism, and a fixing plate 7 for placing items is provided on the placement mechanism.

[0024] Through the linkage mechanism, the user can open the low temperature box 1 and drive several test tubes 11 to be lifted at the same time. With the support of the placement mechanism, the labels of several test tubes 11 are exposed, which is convenient for identification and taking.

[0025] Furthermore, the linkage mechanism includes a connecting rope 3 and a support plate 6. Two cover plates 2 are hinged on the top of the low-temperature box 1. The two cover plates 2 are symmetrically arranged. Two connecting ropes 3 are fixedly connected to the inner sides of the two cover plates 2. Adjacent connecting ropes 3 are symmetrically arranged. Two first guide wheels 4 are rotatably connected to the two sides of the inner wall of the low-temperature box 1. Second guide wheels 5 are rotatably connected to the outer sides of the first guide wheels 4 on both sides of the inner wall of the low-temperature box 1. Each connecting rope 3 passes through each group of first guide wheels 4 and second guide wheels 5 in turn. One end of several connecting ropes 3 is fixedly connected to the same support plate 6, so that when the connecting rope 3 moves upward, the support plate 6 can be driven upward, thereby facilitating the subsequent lifting of the items inside the low-temperature box 1.

[0026] Furthermore, sealing gaskets are fixedly connected to the top and one side of the two cover plates 2, so that after the two cover plates 2 are combined, the two sealing gaskets fit each other on opposite sides, thereby ensuring the airtightness inside the low temperature box 1.

[0027] Furthermore, the placement mechanism includes a placement hole 8 and a rubber sleeve 9. A fixing plate 7 is fixedly connected to the inner wall of the low temperature box 1. A plurality of placement holes 8 are opened at the top of the fixing plate 7. The plurality of placement holes 8 are equidistantly arranged in a rectangular shape. A plurality of ventilation holes 10 are opened at the top of the fixing plate 7. The plurality of ventilation holes 10 are equidistantly arranged in a rectangular shape, and the plurality of placement holes 8 and the plurality of ventilation holes 10 are staggered one by one. Rubber sleeves 9 are fixedly connected to the inner walls of the plurality of placement holes 8. Test tubes 11 are placed on the inner walls of the plurality of rubber sleeves 9, so that the rubber sleeves 9 can wrap the test tubes 11, thereby slightly squeezing and restricting the position of the test tubes 11. Due to the arrangement of the plurality of ventilation holes 10, the cold air inside the low temperature box 1 can flow above and below the fixing plate 7.

[0028] Furthermore, it also includes a limiting mechanism arranged on the outside of the low temperature box 1, the linkage mechanism is connected to the cover plate 2 of the low temperature box 1, and the cover plate 2 of the low temperature box 1 is clamped with the outside of the low temperature box 1 through the limiting mechanism, and the linkage mechanism is conveniently limited and fixed through the limiting mechanism.

[0029] Furthermore, the limiting mechanism includes a positioning plate 14 and a concave plate 15. A slide groove 20 is provided on the outer side of the two cover plates 2. A fixing rod 12 is fixedly connected inside the slide groove 20. A slider 13 is slidably connected to the outer wall of the fixing rod 12. A positioning plate 14 is fixedly connected to one side of the slider 13. Concave plates 15 are fixedly connected to the outer side of the two positioning plates 14 on the outer side of the low temperature box 1. When the two cover plates 2 are rotated to be perpendicular to the top surface of the low temperature box 1, due to the weight of the positioning plate 14 itself, the positioning plate 14 slides downward on the fixing rod 12 while being embedded in the concave plate 15, thereby limiting the position of the two cover plates 2.

[0030] Furthermore, a limiting rod 16 is fixedly connected to one side of one cover plate 2, and a rotating plate 17 is rotatably connected to the outer wall of the limiting rod 16. A slot 18 is provided on one side of the rotating plate 17. A clamping rod 19 is fixedly connected to one side of the other cover plate 2, and the outer wall of the clamping rod 19 is adapted to the inside of the slot 18. When the two cover plates 2 are merged, the rotating plate 17 drives the slot 18 to clamp onto the clamping rod 19, thereby limiting the position of the two cover plates 2.

[0031] Working principle: Rotate the rotating plate 17 so that the rotating plate 17 drives the card slot 18 to separate from the card connecting rod 19, thereby releasing the restriction on the two cover plates 2, and rotate the two cover plates 2 upward. At this time, the cover plate 2 drives the connecting rope 3 to move upward, so that the connecting rope 3 slides inside the first guide wheel 4 and the second guide wheel 5, and then several connecting ropes 3 drive the support plate 6 to move upward. When the top surface of the support plate 6 contacts the bottom surfaces of several test tubes 11, the support plate 6 drives several test tubes 11 to move upward inside several rubber sleeves 9. When the two cover plates 2 are rotated to be perpendicular to the top surface of the low temperature box 1, due to the weight of the positioning plate 14 itself, the positioning plate 14 drives the slider 13 to slide downward on the fixed rod 12, and the positioning plate 14 is embedded in the concave plate 15, thereby limiting the position of the cover plate 2. At this time, the labels on several test tubes 11 are exposed above the fixed plate 7, so as to facilitate the inspection personnel to identify and take the test tubes 11.

[0032] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
